- `GET /info` now includes a `Containerd` field containing information about the location of the containerd API socket and containerd namespaces used by the daemon to run containers and plugins. [moby/moby#47239](https://github.com/moby/moby/pull/47239)
- Deprecate non-standard (config) fields in image inspect output. The `Config` field returned by this endpoint (used for `docker image inspect`) returned additional fields that are not part of the image's configuration and not part of the [Docker Image Spec] and the [OCI Image Spec]. These fields are never set (and always return the default value for the type), but are not omitted in the response when left empty. As these fields were not intended to be part of the image configuration response, they are deprecated, and will be removed in the future API versions.
- Deprecate the daemon flag `--api-cors-header` and the corresponding `daemon.json` configuration option. These will be removed in the next major release. [moby/moby#45313](https://github.com/moby/moby/pull/45313)

The following deprecated fields are currently included in the API response, but are not part of the underlying image's `Config`: [moby/moby#47941](https://github.com/moby/moby/pull/47941)

- `Hostname`
- `Domainname`
- `AttachStdin`
- `AttachStdout`
- `AttachStderr`
- `Tty`
- `OpenStdin`
- `StdinOnce`
- `Image`
- `NetworkDisabled` (already omitted unless set)
- `MacAddress` (already omitted unless set)
- `StopTimeout` (already omitted unless set)

#### Go SDK changes

- Client API callback for the following functions now require a context parameter. [moby/moby#47536](https://github.com/moby/moby/pull/47536)
  - `client.RequestPrivilegeFunc`
  - `client.ImageSearchOptions.AcceptPermissionsFunc`
  - `image.ImportOptions.PrivilegeFunc`
- Remove deprecated aliases for Image types. [moby/moby#47900](https://github.com/moby/moby/pull/47900)
  - `ImageImportOptions`
  - `ImageCreateOptions`
  - `ImagePullOptions`
  - `ImagePushOptions`
  - `ImageListOptions`
  - `ImageRemoveOptions`
- Introduce `Ulimit` type alias for `github.com/docker/go-units.Ulimit`.
  The `Ulimit` type as used in the API is defined in a Go module that will transition to a new location in future.
  A type alias is added to reduce the friction that comes with moving the type to a new location.
  The alias makes sure that existing code continues to work, but its definition may change in future.
  Users are recommended to use this alias instead of the `units.Ulimit` directly. [moby/moby#48023](https://github.com/moby/moby/pull/48023)

Move and rename types, changing their import paths and exported names.
Title: Docker API Updates and Go SDK Changes
Summary
This section details updates to the Docker API, including the addition of a `Containerd` field to `GET /info` and the deprecation of non-standard fields in image inspect output. It also mentions the deprecation of the `--api-cors-header` daemon flag. A list of deprecated fields in the API response is provided. Furthermore, it outlines changes to the Go SDK, such as requiring a context parameter for certain client API callbacks, removing deprecated aliases for Image types, and introducing a `Ulimit` type alias.
